Application filed November 9, 1896. b'efil N0 6111562- (NO modem To @ZZwhom it may concern:

Be it known that I, GEORGE W. GOMBER, a

citizen of' the United States, residing at Conyngham, in the county ofLuzerne and State of Pennsylvania, have invented certain new and usefulImprovements in Talking-Machines; and I do hereby declare the followingto be a full, clear, and exact description of the invention, such asWill enable others skilled in the art to which it appertains to make anduse the same.

My invention relates to improvements in talking-machines of that classin which any preferred individual tablet in a plurality or Inagazine oftablets may be brought into operative relation with the recorder andreproducer.

lhe object, therefore, of my invention is to provide a talking-machinewhich shall have a plurality of tablets and shall combine in closecooperative relationship automatic means for bringing any selectedindividual of t-he series of tablets into operative relation with thevibratory diaphragm (by which term I desire to comprehend a recorder orreproducer) by simply droppinga coin in the slot prepared for itsreception and pushing one of the series of buttons corresponding to theselected tablet.

Referring to the drawings, Figure l is a front elevation of my improvedtalking-machi ne in its com plel e operative position, showing thediaphragm in its initial position. Fig. 2 is a top plan view of Fig. l.Fig. 3 is a sectional View of Fig. l on line A A looking toward themagazine and showing the position of the carriage and parts carriedthereby by dotted lines. Fig. Liis a sectional view on line A A lookingto the left. Fig. is an end elevation from the right Side. Fig. 6 isasectional view on line B B of Fig. l looking to the right. Fig., 7 is alongitudinal section of the tablet-cylinder and the shaft therefor. Fig.8 is a detail perspective View of my preferred form of adjustableI stop.Fig. 9 is a dei-ail side elevation of the idler and reciprocatingsleeve. Fig. l0 is a detail perspective View of part ot' the controllingmechanism for the outer end of the carriage. Fig. ll is a detail viewshowing the supporting-axle and vthe sleeve and the head 5 carriedbysaid sleeve.

While, as previously stated, the essential Vfeatures of my inventionreside in the provision of a plurality of tablets and means forselectivelybringing them into cooperation with the transcribing-stylus,yet there are certain accessories which bear an important relation tothese elements and which will be vhereinafter referred to as a part ofmy complete operative talking-machine.

In the employment of a magazine of tablets for the purpose stated lprefer to adopt that particular form of rotatable tabletholderillustrated, consisting ot' a iiXed shaft l, secured at one end by aretaining-clamp 2, af-

Iof the snugly-fitting sleeve 4, to the inner end of which is rigidlysecured the fixed head 5, while to the outer end thereof is detachablysecured the removable head (i. The head 6 I prefer to detachably secureto the hub or sleeve L by providing in the end of said hub an ellipticalbore 7, adapted to accommodate a clamp 8, formed to register with theelliptical opening when it is desired to remove the head and to resttransversely across said aperture and against the outer face of the headwhen in its securing operative position.

1f preferred, an individual releasing device for each of thetablet-cylinders may be provided, though it is thought that by makingprovision for the simultaneous removal ot' all the tablets such meanswill be found amply suficient to meet the requirements, as it will beseen that each of the shafts provided for the tabletcylinders is Wellanchored in its bearings provided in the iixed head, thus enabling theremovable head to be taken away, allowing the tablet-cylinders to remainin their respective positions until the ends of their shafts are removedfrom their bearing-seats.

Upon the housing 3 for the motor I erect the standards 9 10, which areadapted to afford seats for various elements hereinafter referred to. Insubstantially the central section of the standards 9 10 I providesuitable bearings 11 for receiving the rotatable shaft 12, and upon saidshaft, intermediate said standards, though nearer the former, I mountthe idler 13. 'Ihe inner end of the shaft 12 extends through itsbearings 11 in the standard 10 and is provided with the pulley orsprocket 14, adapted to cooperate with the pulley or sprocket 15,secured to the axlesleeve 4 on the innerend of the tablet-magazine. Bymeans of said sprockets or pulleys, as the case may be, said magazine isrotated. Located upon the inner side of the idler 13 I provide thereciprocating sleeve 16, which terminates in the head 17 and is so keyedor feathered to the shaft 12 that it will rotate therewith, but willalso have a reciprocatory movement thereon. The contacting faces of theidler 13 and the head 17 are provided with frictional points or pins 1819, adapted for engagement with each other when the sleeve is movedtoward the idler by the downwardly-extending arm 20, secured to thecarriage-frame 2l and arranged to bear against the face 17a of the head.

The carriage 21 is held in its operative position by the shaft 22,mounted in suitable brackets or supports 23, attached to a part of theframe 24, and is adapted to reciprocate on said shaft through the mediumof the barrel or sleeve 25, loosely mounted on the shaft 22 andextending to the right suiiiciently to provide a point of attachment andsupport for the diaphragm-carrying arm 26. By this arrangement thebarrel or sleeve 25 may be freely moved in either direction upon theshaft 22, enabling the diaphragm to be moved into 'contact with thetablet. I prefer to-so mount the arm 26 upon the barrel 25 that it willtightly grasp the same and have frictional contact therewith, permittingthe diaphragm to be raised or lowered by simply overcoming thefrictionalgrasp,when the diaphragm will be held in au adjustedposition-that is to say, the arm 26 is provided with the collar 26,which tightly fits around the barrel 25, and while the frictional graspof said collar may be overcome it will be understood that it will clingsufficiently to the barrel to hold the arm 26 in an adjusted position.

The carriage-frame 21 extends to the front part of the machine and restsby its extreme outer end 21 upon the cam-faced shaft 27, while its innerend is rigidly secured to th barrel 25 by means of the body 2S.

The outer end of the carriage-frame 21 has depending therefrom theobliquely-disposed finger 29, adapted to raise the inner edge or blade30 of the shaft 27 when it comes in contact- With the elbow 31, providedwith the frictional rollers or sleeves 32 and 32a.

Preferably upon the upper surface of the body 28 I secure the slottedend 33 of the spring 34, provided upon its upper surface,

near the intermediate part thereof, with the threaded block 35, and uponthe under side of its ou ter end with a similar block 36, adapted,respectively, for contact with the threaded shafts 37 38, by means ofwhich the carriage is moved in opposite directions. The shaft 37 isprovided with threads running to the left, While the shaft 3S hasthreads running to the right, and as there is sucient play permitted tothe spring-arm 34 between the shafts 37 38 only one of the threadedblocks is in contact with itsishaft at the same time, providing that thecarriage will be moved to the right or the left, as the case may be. Theshaft 38 is provided with a suitable bearing in the upper end of thestandard 9 and with a graduated pulley 39, having the faces 40, 41, and42, the iirst being designed to connect directly with the motor in thehousing 3 by the belting 43. The face 42 is designed to connect bybelting with the idler 13, while the face 41 cooperates with the pulley44, provided at an opposite point thereto upon the shaft 37. The shaft37 is also properly seated in bearings 37, provided in the extreme innerand upper-extensiops 37b of the standards 910. The inner end of theshaft 3S passes loosely through an aperture provided in the upper end ofthe standard 10 and extends into engagement with the bearing-point 45,held in an adjusted position by the downwardlyextending section 46 ofithe lateral continuation 47 of the standard', 10. It will be understoodthat all of said shafts may be provided with bearings of this characterin order that a minimum amount of friction may result, though anydesired fogrm may be employed.

The lateral extension 47 is designed, in addition to providing a bearingfor the eXtreme end of the shaft 38, to carry or suspend thesprocket-frame 48, in the outer ends of which are mounted the sprockets4H 50, intended to be actuated by the sprocket 5l, mounted ou theextreme end of ,l the shaft 38. These sprockets when properly connectedby a suitable belting are intended to act upon one of the sprockets 52,secured to the inner end of the shaft of the tablet-cylinder, and as thesprocket 51 is disposed slightly above the sprockets 49 50 the beltingwill reach across from the under side of said sprockets and freelycontact with any preferred one of the sprockets 52 as its accompanyingtablet'is broughtinto cooperation with the diaphragm. For this purposeit isthought that a belting constructed of suitable pliable materialprovided with eyelets for engaging with the teeth of the sprockets willbe found most suitable, though ordinary leather belting provided withsuitable apertures to ',receive the sprocketteeth will, it is thought,be found to be stiflicient to meet the requirements, yet by protectingthe edges of said apertures with metal eyelets a much longer life isimparted to the belting, rendering it more desirable for the purpose.

In order to hold each of the shafts 4 of the IIO tablet-cylinders in itsoperative position and to accommodate a suitable form of bearingtherefor, I provide upon the fixed head the inwardly-extending sockets5, having a sufficient bore to loosely receive the inner ends of thecylinder-shafts 4, which are received and held in position by theadjustable bearingpoints 5b, axially seated in the ends of said sockets.The extensions or sockets 5 also provide a seat upon their upper surfacefor the reception of a series of disalined stops 53, so located thatnone will move in the plane or path of the others and designed tocontact with their respective tumblers when the desired tablet is inapposition with the diaphragm.

Mounted in the rear part 24 of the frame of the machine, at a point on aline with the disalined stops 53 and designed to contact by propermanipulation with their respective stops, I provide a series of tumblers54, arranged to reach through suitable bearing seats or apertures 55 inthe frame, While pivotally connected to theinner ends 56 ofsaid tumblersis the operating-bar 57 for each ofthe tu mblers 54, preferablyextending upward from the point of their pivotal connection with thetumblers on the rear side of the frame and parallel therewith. Saidapertures 55 are of suficient extent to admit of a free upward movementof the tumblers 54. By this arrangement of the apertures the tumblers 54will rest upon the lower end thereof and check the downward movement oftheir respective stops; but when the magazine is reversely rotated eachwill move out of the path of its stop when contacting therewith from thelower side. Each of the bars 57 is provided, preferably nearits upperend, with a pivotal connection or bearing 58, secured to the rear sideof the frame. Designed to normally withdraw the tumblers 54 is thespring 59, one end of which is anchored in the inner edge of the bar 57,While the free end thereof is arranged to bear against the frame, thuswithdrawing the tumblers. To the upper ends of the bars 57 I pivotallyconnect the operating-lever 60, arranged to extend through suitableapertures 6l, provided in the frame, to the front side thereof, wherethey terminate in or connect with suitable manipulating-buttons 62 formanual control. In order to dispose the series of operating-buttons thusprovided within a convenient area and position, I prefer to graduate thelength of the series of bars 57, arranging that the bar upon the rightor left shall be shortest or longest, as may be preferred, andgraduallyincreasingordiminishingthelength of the other bar, the case maybe, resulting in the arrangement of the buttons in a line with eachother, substantially as shown in Fig. l. This is a preferred form ofarrangement for the operating-buttons, though it will be understood thatany convenient and preferred plan may be adopted for this purpose.

For cheap, and consequently expeditious, construction I prefer to formthe bars and -plete series of stops.

tumblers 57 and 54, respectively, of wood, arranging that a simplesaw-mark in the inner edges of said bar will provide a seat for thespring 59, though for more permanent construction it will be understoodthat these parts may be formed of any preferred material. By thedisposition made of the spring 59 it will be observed that therespective button of each bar will be held normally outward, when apressure upon said button will enable the tension of the spring 59 to beovercome, thus forcing the tumbler 54 into the path of its respectivestop, all of which for convenience are designated by the numeral 53.

Frein the drawings and specification in this case it will appearthat itis the function of the stops 53, respectively, to engage each itsappropriate tumbler 54, and thereby to determine automatically which oneof the tablets of the magazine shall assume operative relations with thevibratory diaphragm. The actuation of one tumbler causes the mechanismautomatically to select a particular stop and no other. In like mannerthe actuation of another tumbler causes the selection of another. stop,and so on throughout the com- Now the employment of cooperative stopsand tu inblers is in tended only to illustrate one mode of accomplishingan object that may be accomplished in a variety of ways and isrepresentative in the broad sense of any mechanism that is adapted toselect any one of a series of tablets in preference to any other.Therefore for brevity and convenience I denominate such mechanismtablet-selective mechanism, intending thereby to include any mechanismthat is adapted, through the manipulation of a meinber-in the presentexample one of the tumblers 54-to select for operative relations withthe vibratory diaphragm any individual of a series of tablets that maybe determined upon irrespective of the relation in which the tabletselected may stand toward the other tablets of the series.

The cam-faced shaft 27 is mounted in suitablev bearings 63, located inthe outer ends of the brackets 64, the latter being so connected to thestandards 9 l0 that said shaft will be held slightly above thoughparallel with the shaft l2. At the foot of the standard l0 and at theforward edge thereof I provide the pivotal seat 65, arranged to receivethe lower end of the standard 66, which extends upward parallel withsaid standard and is provided upon its upper end with the obtuse angle67, presenting a cam-face 67 a for contact with the friction roller orsleeve 32a, mounted upon the elbow 3l, secured to the shaft 27. 'lo theopposite end of the shaft 27 and extending inwardly therefrom parallelwith the blade 30 I provide the controlling-lever 68, which has pivotalconnection with the crank-arm 69 by means of the link 70. Said crank-armis rigidly connected to or integrally formed with the rocking shaft 7l,which is disposed parallel with the longitudinal line of the ma-l IIOchine and is mounted in suitable bearings 72 and consists of thebody-section 73, the transverse arm 74, and the terminal branch 75,adapted to bear upon the upper edge of the tumblers and prevent theupward extension or movement thereof. The connection between the shaft27 and the rocking shaft is so made that the elevation of the edge orblade 30 will result in the depression of the terminal branch 75 intocontact with the upper edge of the tumblers, preventing, as previouslystated, an upward movement thereof until said branch has been elevatedby the corresponding depression of the blade 30.

In order to automatically provide for the actuation of the terminalbranch 75, I provide near the outer end of the carriage-f rame 21 theinclined guide or radially-disposed finger 29, which will, as thecarriage moves to the right, contact with the friction roller or sleeve32 and cause the same to ride upon its inclined face, resulting in theelevation of the inner edge or blade 30 and the partial rotation of thecam-faced shaft. The elevation resulting from this contact of thefriction-roller with the inclined face of the depending linger 29 causesthe friction roller or sleeve 32a to ride upward against the outer faceof the lever 66 until the obtuse angle 67 has been reached, when theupper end 67a of said lever will be forced outward against said sleeve,causing the same to ride upon the inclined face 67, through the actionof the spring 76, so disposed that its free end will bear downward uponthe outward extension 66a of the lever. The opposite end of the spring76 is suitably anchored at any preferred point where its oflice may bemost effectively performed.

The operation of my improved automatic talkingmachine may be describedas follows: That is to say, the carriage is placed in its initialposition at the extreme left end of the threaded shafts,when thediaphragmarm is depressed, overcoming its frictional grasp upon thebarrel 25, bringing the diaphragm into the plane of the surface of thetablet, which has first been placed in position by a pressure upon itscorresponding button,

duly labeled to indicate said tablet. The motor is then started, eithermanually or automatically, by aid of a suitable prime mover, when thethreaded block 36 will engage with the shaft 38, resulting in thelateral movement of the carriage in unison with the threads provided onsaid shaft, causing the stylus, with its accompanying diaphragm, tofollow the line of record provided on the tablet until the extreme outerend thereof is reached, when the depending radially-disposed finger 29will engage with the frictionroller 32, elevating the elbow 31, andthereby causing the friction-roller 32 to travel upward upon the face ofthe lever 66 until the obtuse angle 67 thereof is reached, when theaction of the spring will force said lever outward, contacting the face67 of said lever with said roller, and complete the elevation of theblade 30, incidentally causing said blade to act upon the outer end 2luof the carriage and forcing the threaded block 36 out of engagement withthe shaft 38 and bringing the threaded block 35`iinto coperation withthe shaft 37, effecting the reverse movement of the carriage. Theelevation of the blade 30 also results in the upward movement of thecontrolling-lever 68, acting upon the rocking shaft 71 in such manner asto cause the terminal section 75 thereof to move downward into contactwith the upper edge of the tumbler, holding the same in a horizontalposition, preventing a continued reverse 1novement of thetablet-magazine.

It will be understood that each of the buttons controlling itsrespective tumbler will be labeled or designated in any preferred mannerto correspond withltbe subject or selection inscribed upon the tabletlocated at its respective stop, enabling the operator to make aselection of a subject and bring the same under the reproducing-stylusby a simple pressure on the button.

The adjustment of the several parts is so made that the contact of thetumbler with its stop will place the desired selection under the stylus,bringing the sprocket 52 into engagement with the belting upon thesprockets 49 50, which latter, as previously set forth, are actuatedthrough the medium of the lsprocket 5l, located upon the shaft 38. The

movement, therefore, of the shaft 38, in addition to a positiveactuation of the carriage, also rotates the tablet-cylinder, enablingthe diaphragm to travel in harmony with the line of record.

In order to provide aconstruction for the tablet-cylinder which willcompensate for the expansion and contraction incident to changes in thetemperature, I prefer to provide that the surface of the shaft 4 for thecylinder-body 4J shall be suitably roughened or finely corrugated, uponwhich is shrunk or forced the body proper, 4b, preferably made of lightporous wood, cork, or the like, while upon the outer surface thereof Isecure a covering 4, of a flexible and loosely formed fibrousmaterial-such, for instance, as canvas, canton-flannel, or the like-theobject being to provide for the free expansion and contraction of thematerial forming the tablet.

The stops 53 may consist for cheap and eicient construction of a seriesof screw-threaded lugs or points properly seated in the outer face ofthe sockets in such manner that each will engage with its respectivetumbler and be disposed in an entirely-different path from the other, orsaid stops may consist of the adjustable device shown in Fig. 8 andconsisting of the plate 53a and the integrallyformed point 53. In eitherend of the plate I provide the slotted apertures 53", designed to permitlongitudinal movement of the plate 53, that the stop may be properlyadjusted. If the form of stop consisting of the threaded lug or point beemployed and it should be lOO IIO

IZO

necessary to readjust it after it is seated in the outer face of thesocket, such readjustment can easily be effected by simply bending thepoint in the direction desired, which of course will be readilyappreciated.

Upon the shaft 12 ismounted the idler 13 and the sleeve 16, aspreviously stated, andsaid sleeve is designed to coact with thedepending arm 20, provided upon the carriageframe 21, as follows: Whenthe carriage has moved back into its initial position, the bearing-block35 will drop into the groove 77, (said groove being a reduced portion ofthe shaft 37,) when the blade 30 will tend further to elevate thecarriage-frame 21 and its accompanying depending arm 20, bringing it tobear against the face 17u of the sleeve, forcing said sleeve and thefriction-point 19 thereon into engagement with the idler and thefriction-point 18, secured thereto, thus connecting said idler to theshaft and resulting in its rotation and incidentally rotating thesprockets 14 15, causing a reverse movement to be imparted to thetablet-magazine until the stop bearing upon the upper side of itstumbler is moved entirely around to contact with the lower side thereof,thus bringing the magazine to a full stop, owing to the interposition ofthe terminal section 75.

It will of course be understood that I do not wish to be confined to theuse of belting as a means 'for communicating power from one pulley toanother, as toothed gearing or other equivalent may be used, ifpreferred. For instance, the sprockets 14 15 may be toothed gearingarranged to mesh with each other in the usual manner, thus dispensingwith the necessity of other means for forming connection. The same maybe said with reference to the sprockets 51 52 and other parts now shownas connected by belting.

In order to make it clear how I retain a flexible covering of felt,canvas, or other preferred material upon the porous body of thetablet-cylinder, I will state that said covering may be so placed thatthe projecting edges thereof will extend past the ends of the body ofthe cylinder, where they may be drawn inward toward the shaft and theresecured against the ends of the body by a suitable retaining-plate 4dand retaining-screws ete or other preferred means, taking through saidplates into the body.

In order to provide that the tablet-magazine will be reliably held in anadjusted position, to the end that the subject-matter upon any preferredtablet may be transcribed, I arrange the locking mechanism for themagazine, (more clearly shown in Figs. 3, 5, 6, and other views,) andwhich I will describe by stating that the sprocket or gearing wheel 15is provided upon the face thereof or other preferred point with a seriesof notches or teeth 78, adapted for engagement with the detent or pawl79. The lower end of the detent 79 is pivoted in a suitable seat 80,mounted at any convenient point to enable it to perpreferred one of thetablets is being transcribed.

The operation of the locking device may be stated as follows: When theelbow or inner edge of the blade, to one of which the linksection 82 isattached, is depressed,the crankarm 81 will be moved downward, forcingthe free end of the detent into engagement with one of the notches orratchets 78, thus locking the sprocket or gearing 15 against movementuntil the detent is Withdrawn. The downward movement of the elbow orblade just referred to occu rs only when the diaphragm is brought intocoperation with the tablet, consequently resulting in holding themagazine in a fixed position until the diaphragm has traveled the entirelength of its tablet. When the stylus has transcribed-the entire line ofrecord, the diaphragm is automatically returned to the starting-point,as already described, through the elevation of the blade 30, which actresults in the withdrawal of the detent 79 from engagement with thesprocket 15, permitting another selection from the magazine-tablets tobe made.
